Abstract:
An experimental study of the copepod Mesocyclops edax documented that females which reproduced throughout their lifetime survived at a lower rate than unmated females which did not reproduce. This cost of reproduction was most apparent in animals receiving periodic, non-lethal temperature stress. However, among reproductive females, no significant correlations were detected between reproductive output and survival, suggesting caution concerning the application of cost of reproduction arguments to a population of females in which clutch size is seen to vary.

01:11Testing a Claim about Mean: Known Population SD
Estimating a population mean requires the samples to be distributed normally. The data should be collected from the randomly selected samples having no sampling bias. The sample size needed to be higher than 30, and most importantly, the population standard deviation should be already known.
In most realistic situations, the population standard deviation is often unknown, but in rare circumstances, when it...
